The reason I recommend and continue to use a dedicated DAC is straightforward: It makes my music sound better.There are lots of dubious audiophile tips and tricksto improving audio quality, and some people will never be satisfied, but using AudioQuest'sDragonfly Black has made a difference to my ears.It's not a "night and day" difference like the one you'd notice when stepping up to a great pair of headphones, but it's there. Instead, the DragonFly Black has helped me discover nuances in some of my favorite songs that I'd never heard before. As I said in my original review,I only appreciatedthe difference after getting used to the way music sounded through the DragonFly Black and then going back to my MacBook Air's headphone jack.Most audio gear is big, bulky, and expensive, which is why I tend not to recommend it to most people. I've had great experiences using Apogee's Duet IIand Nu-Force's headphone amps in the past, but they require a serious monetary investment.The DragonFly Black looks like a flash drive. You plug your headphones into its one port, and that's it.There's something to be said about simple, subtle audio gear, and hopefully other companies will begin to offer similar products. You can even use this DAC with your iPhone or Android phone with the right adapters, which is great news for audiophiles who travel often.As it stands now, I've spent almost a year using AudioQuest's DragonFly Blackand I don't plan on stopping. Anyone who enjoys music and wants to make the most out of listening to it at their desk should seriously consider trying one for themselves.AudioQuest DragonFly Black USB DAC, $98.75, available at AmazonDON'T MISS:24 headphones that are actually worth your timeSEE ALSO:15 Bluetooth speakers that are actually worth your timeJoin the conversation about this story
